Specification of Letters Patent.

Patented Ap 1907.

Application filed July 25,1905- Serial No. 327.705.

To albwho m it 1nayc0neern.-

Beit known that I, Gnonen N.I1INCHMAN, acitizen of the ,United States, residing at Webster Groves, in the county of St. Louis and State of Missouri, have invented a certain new and j useful At'ldingdiachine, of which thefollowing' issuch a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

. My inventionrelates to an adding machine, and more particularly to that class of adding machines'in which the individual items, as well as the totals, are printed upon a strip or sheet of paper.

The object of my invention is to provide scribed a symbol or character has been printed adjacent to each total to distinguish the total from the items. According to my invention, however, I print adjacent to each item a symbol or character preferably polygonal in form,whereby the items and totals aredistinguished and at the same time means is providedfor facilitating the checking of the items. Y

in the accompanying drawings, which ill ustrate my invention applied to a machine like that shown in my prior &[)1')ll(ltt10l1S Nos. 287,118 and 287,119" of November 13th, 1905, Figure 1 is a vertical central section through the upper and forward part of the machinml ig. 2 is an enlarged view showing the gearing for controlling the item sign and Fig. 3 is a view illustrating the work done by the machine.

Like marks of reference refer to similar parts in the several views pi the drawings.

' 5 is the casing of the machine, within which is the usual framework 6 for supporting the various parts.

7 are the addingwheels mounted upon a shaft 8 provided with a comb 9. Below the adding wheel shaft 8 is a shaft 10, upon which are mounted idle wheels 11 which are adapted to mesh with the adding wheels 7. Meshing with the idle wheels 11 are intermediate wheels 12 mounted upon a shaft 13 provided with a comb 14,5513 shown in Fig. 2. The intermediate wheels 12 are driven by means of an axially movable wheel 15 moving upon an axle 16. The intermediate wheels 12 mesh with printing wheels 17 mounted upon a shaft 18. The adding wheel 7, idle wheels 11, intermediate wheels 12, driving wheel 15 and printing wheels 17 are indicated in dotted lines in Fig. 1. The peration of these wheels in adding numbers is identically the same as in my prior applications above referred to. The adding wheels 7 are normally out of mesh with the-idle wheels 1.1 so that when the individual items are placed in the machine bythe operation of the keys, the printing wheels 17 will be positioned from the driving wheel 15 through the intermediate wheels 12 without in any way allecting the adding wheels 7. After the number has been printed, lmwever, the adding wheels 7 are moved into mesh with the idle wheels 11, so that when the printing wheels 17 are returned to zero on the opera- The individual items, as well as the totals,

are printed upon a strip of paper 21, which strip passes and the printing hannners 22. hammer 22 is supplied for each printing wheel 17, and there is also an additional hammer for co-operation with the type for printing the item symbol, as will be hereinafter described. The printing hammers 22 are o perated by means of a printing slide 23 in the usual manner. The strip of paper 21 is supplied from aspool 24 mounted on a shaft From the spool 24 the strip of paper 2-1 passes around a guide 26, thence between the p rinting hammers 22 and the printing wheels 17 and around a second guide27 to the feed rolls 28 and 29, from which it'passcs out through between the printing wheels 17 A printing a discharge opening 30 at the top'of the machine 'lhe shove described. parts are like thosein my print" appiicatig-ns al -r;ve rot erred to and need net more particularly described.

Loosely mounted on the shaft is a disk position.

symbol preferably consists of a polygonal figure and may be in the form of a lozenge containing the letter S, as shownin Fig. 3 of the drawing. This type lO is arranged as shown in the drawing so as to normally be in the path of the hammer 2'2 and'i g held in this position. by means of a pawl 41 pivoted on a shaft 4-2 and provided with a spr' 1g 43. This pawl ll engages with a notch et in the disk 39 to hold the t *pe 4-0 in its normal The disk 39 is also provided with a notch 45 to hold the type .-10 out of printing position when the total is taken, When the adding wheel shaft 8 is rotatedto return the adding wheels 7 to zero and thus transfer thetotal to the printing wheels 17, the/comb 9 will come in contact with the tooth 36 on the disk 35 and so rotate the said diskin the direction of the arrow in Fig. 2. This motion will be vcominunit ated to the disk 36 by -.means of the teeth on the saiddisk so as to move said disk in the direction of the arrow in Fig. 2. This movement will be tommunicated by the fingers .17 and 38 to the disk39 so as to move the said disk on thc shaft 18,

and, consequently, move the type 40 -down-' wardly so as to be out of the path of the printing hammer 22.- When moved in this position the pawl 41 will engage with the notch 45 in the disk 39 so as tohold the type i 40 out of printing positionuntil the various wheels are returned to their normal position,- when the 0111i?- 14 in the shaft 13 will engage with a pin 46 on the disk as, so as to return the type it) to its normal or printing posi- ,tion. The pin 46 pIOjOLtS at both sides of the disk 36 and is adapted to come in rontart with the comb 47 which forms the'stop for the intermediate wheels 12.

It will be seen from the above that whenever an item is written into the l'llilf lll llt the .tooth 36 adapted to lre engaged tvpe 40 will remain in'its normal or printing position and adjaren't to ea'h item printed 'thetype 40 will print a lo'zengesl1aped symbol or character 48, as shown in Fig. 3 of the drawing. When, however. the total is taken the type 40 will'he moved out ol printing total.

ea 1,0s

position so that the sign will "not' be printed adjacent to'the total.

In this manner the. totals are readily distinguished from-the items and in addition means is-provided" whereby the items may be oheoked'over a; number 0t tlnies without ha ihty of c'onfusing the check marks. This-is oitenneeessary, especially ln-long columns of figures and with the ordmary method 'otwriting itemswithout an item symbol the check marks'are liable to be confused. Vith a polygonal It QIII SYIHlZOl, however, such as l; use',the items may be. ehetked over a number of times without any liability of contusion, as a ditl'erent side or angleof the item symbol may be. used during ear-h time of checking, thus, forinst am; e', uponjlirst checking the items theitem .1 heck may he made against the upper left hand-side of the item symbol. At the second checking it maybe made against the upper right hand side, and

.so on, and after tlie'sid'es'have, been. re-. turned the angles of the symbol may be utilized.

Having fully described my invention, what I claimas new and desire to secure by Letters Patent oi the United States is. v

- 1. In an adding machine, the combination with adding merhanism, of means for automatically print ng an item' symbol n conjunction with each individual item, said means being inoperative when printing a 2. In an adding machine, the combination with adding mechanism, of print-mg devlces for printing individual items and totals, an.

auxiliary printing device for printing a symbol adjacent to each item, and means for preventing said auxiliary'device from printing when taking the total.

3. In an adding machine, the combination with adding methanism, of printing devices inrluding an item symbol, means for transferring the total from said adding mechanism to said printing devire, and connections operated by the transfer of the total for proventing said item symbol from printing.

4. In an adding machine, the combination with adding wheels, of printing wheels including an item symbol, means for transferring the total from said adding wheels to said printing wheels, and connections operated by the transfer of the totals for preventing said item symbol from printing.

5. In an adding machine, the combination with adding mechanism, of printing devices .in luding an item symbol normally in print said item symbol out ot'printing position,

and means for returning said item symbol to printing position.

6. In an adding machine, the combination with adding mechanism, of printing devices icrprinting individual items and totals, an huxiliary printing device for printing a po- 5 Lygonal symboladjaeent to each item, and meansifor pret enting said auxiliary device from pxinting when taking the total,
